You're the one that is bringing that up, not armydoc. Again, I say, it is absurd to say that I, as a Catholic, must agree with everything the Pope says.
We are not talking about an off-handed papal comment like, "Would you hand me that glass of water?" (when in fact the glass is full of soda). We are talking about a papal teaching that is in the Catechism. Please explain why it is "absurd" to say that you, as a Catholic, should agree with everything the [Pope & Catechism] teaches. Do you think Catholics can just pick and choose for themselves (outside of the infallible dogmas) which Catholic teachings in the Catechism do and do not belong to the "authentic magiseterium"?
